Petrichor

Petrichor

Petrichor is an opinionated game-agnostic C++ modding framework written for:

• Embeddability
• Flexibility
• Simplicity
• Safety
• Power
• Speed

The language we chose is Luau, a fork of Lua 5.1. We chose this language for its sandboxing, native compilation, dynamic typing, and overall elegance when writing mods.

Dependencies

• Luau (vendored)
• miniz (vendored)
• sol2 (vendored)

Architecture

petrichor_run(IPetrichorHost& host, std::vector<std::string> formats)
↓
Loader      ← Iterates through mods folder
↓
Compilation ← Compiles preludes, host modules, and mods with Luau
